` s claims. (ci. 242-;1'461) in 'ore lin diameter,A with such'a low resistance to separation, rthat even its own weight will be suf- Iicinttb cause'the strand to break. Such strands asthey come from the machine are rolled up into balls, "seine of which may be as great as two feet in diameter and a foot high, the ball being rolled 'up in the `usual way such that when it is unwo'und and fedV into the machine where iti is used, it is consumed from the Ainside ofthe cylindrical ball outward. The `order of unwinding 4these big iballs, is that the inner turns are Figure'z :snows a pian kView of the' dev-ice suomi in LFigure -1. t Y

taken oi up and down the cylinder; making the 'cylindrical ball hollow until graduallyy even outside "turns `are used up.

The unwinding of these balls progresses satis,- facto'rily'while most ofthe center portion of the Figure 4 'shows 'a top view looking down at the `'topof Figure 3.

Figure 5 shovvs'a viewsimilar to Figure 3 with `the ballof vyarn partially used up, and,`

rFigure 6 shows a plan View of the condition shownin Figure.

The 'container itself is extremely 'siinple i in design. It comprises a base member l which as shown `in Figure 1 has a V shaped central section with open'straight sides -2 and 3 which are preferably parallel, and end Walls 4 and 5 of metalor other suitable material, which end walls form vsegments of arcs as indicated morelclearly in Figure 2 whereinjthe center line 0 0 parallel to' the sides 2 and 3 is a diameter of thejcircle upon `which the Walls 4 and 5 are formed. As indicatedpmoreclearly in 'Figure 1 these -side elements 4 and 5 are inclined at a slight angle approximately '10 or somewhat less Vso as to make the lower end of the container slightly smaller in diameter than the upper end. The

` V shaped base 4element I has sloping sides inball is 'being used up, but when the strands 'of the outer ball are being used up, the ball usually collapses and )some of the turns are apt to snare up when they are being fed from the vlower turns of the ball. In other words, when the ball begins to collapse the top turns fall over the turns underneath and in practically all cases unless special precautions are taken to see this does not happen, the strand is sure to pull apart.A

In the present invention this diiculty is overcome and means are automatically provided whereby the entire ball may be used Aup without in any way 'touching or arranging the ball 'at any time. A

In the present invention the ball falls apart in such a way that the turns remain uniformly supported so that the yarn at allV times may be drawn whether it is the bottom layer or some other turns nearer the top of the pile.

The method by which this unwinding of the ball is accomplished lwill be more clearly under stood from the description given in the specification below When taken in connection with the drawing, 'in which:

Figurel shows a section in elevation through the center of the container in which the yarn cylinder is placed. f

clined upwards from the centeru axis 6 perpendicular `to the sides of the base 2 and 3. While the open ends at 2 'and 3 may if desired, be closed. ina broad frame extending. in an arc substantially bigger and further out than Ythe arcs 4 and 5, it is more desirable to leave the sides 2 and 3 open provided nothing will interfere with the arrangement which the cylindrical ball will naturally take. In the present invention the ball is placed as indicated in Figures 3 and 4 when it is completely full.

It will be noted from these gures that the cylindrical ball 1, when full, rests substantially only at `the upper corners 8 and 9 of the inclined surfaces I0 and Il respectively of the base member I. The ball itself is suliciently yielding so that it will rest uniformly within the arched sides 4 and 5 of the container. The ball is wound in such a way (as indicated more clearly in Figure 4) so that it may be unwound from the center turns l2.

It will be evident from consideration of Figures 3 and 4 `that the ball will hold its position in the frame while the inner portion of the cylinder is used up. It is only when the inside hole has a diameter extending approximately to the turn marked A that the ball begins to fall apart. As it falls apart it assumes a position generally indicated in Figures 5 and 6.

In its unwinding as the ball is used up from this point, the lower turns of the ball begin to slide inward along the inclines Ill and Il at the same time that the upper turns fall outward at the sides of the frame. 'Ihe inner lower turns in this way become elongated into an elliptical shape lying crosswise at the bottom of the frame, while the outer top turns of the cylinder of Figures 3 and 4, substantially maintain their form, gradually lowering their position towards the base of the frame, but resting against the side walls of the frame. In Figure 6, therefore, the turns which are more nearly elliptical as for instance the turns I2' are at the lower side of the ball as the ball collapses, but act to keep successive layers of yarn in their original relationship preventing any snarling right up to the Iend of the ball. When the yarn cylinder collapses therefore, the bottom supporting turns which contact the base of the frame only in the corners leaving the inclined surfaces entirely exposed, begin to edge slightly inward toward the Vertex of the base, and support together with the sides, the weak ball with its turns in substantially the same relationship. The base is only partly covered. 'I'he ball or cylinder will therefore be completely used up without danger of the yarnbreaking.

It will be understood from the description given that the construction of the frame may be slightly varied dependent upon the size and shape of the ball. In all cases however the purposes of the construction is such as to make the inner turns when the cylinder disintegrates always feed in the same consecutive order until the yarn is lused up.

Various size frames must of course be used to accommodate the various sizes of rolls, the general distinguishing feature being that the walls are sloped inwardly downward with a base with an inclined slope so that the ball or roll will fall apart and disintegrate in the correct manner.

Having now described my invention, I claim:

l. A frame for holding a cylindrical ball of yarn filler which is unwound from the inner turns outward, said frame comprising a basel member having plane surfaces sloped downward to a common center line, the outer peripheral edge of the base member being in the shape of an arc of a circle, and end wall members attached to the base at said peripheral edge, said end wall members being inclined outwardly at a slight angle and of a size adapted to support the cylindrical surface of the ball.

2. A holder for holding cylindrical balls of yarn fillers wherein the yarn is to be 4unwound from the inside layers outward, comprising an open frame having curved walls in which the ball is adapted to nt with the cylindrical surface of the ball touching the curved walls, a base supporting said walls having a surface inclined from the edges supporting said walls to the central portion of said base.

3. A holder for holding cylindrical balls of yarn fillers wherein the yarn is to be unwound from the inside layers outward, comprising an open frame having walls shaped to fit the cylindrical surface of the ball at the top of the walls and tapering inwardly towards the bottom of the walls and a base supporting said walls having surfaces inclined towards a central section of the base.

4. A holder for holding cylindrical balls of yarn fillers wherein Athe yarn ller is to be unwound from` the inside layers outward comprising an open frame having inclined side walls with a curved inner surface, a base member supporting said side walls, said base member having plane surfaces inclined downwardly from the edges where they are joined to said walls.

5. A holder for holding cylindrical balls of yarn fillers wherein the yarn is to be unwound from the inside layers outward comprising an open frame having an elongated base with arcuate end, sections. a pair of side walls joined to said end sections having a similar curved shape and extending upwards from said base at a slightly outwardly inclined angle, said base having surfaces inclined downward from the edges at which said walls are joined towards an intersecting central portion.

6. A holder for holding cylindrical balls of yarn wherein the yarn is to be unwound from the inside layer outward comprising an open frame having an elongated base member with convex end sections, said base having surfaces sloped upwards from a central section to the convex edges of the base, side walls having aconvex shape joined to the base at the convex ends thereof, said side walls extending upwardly and slightly inclined outwardly and adapted to receive the cylindrical balls of said yarn filler.
